Four pedigrees, each with two or more cases of congenital superior oblique palsy among immediate family members, are presented. Except for a single case report in 1926, this disorder has not been known to occur in a hereditary manner. Theories of pathogenesis of congenital fourth cranial nerve palsy are discussed, with special reference to the hereditary(More)
A 15-month-old boy with rapidly progressive proptosis had an unusual malignant germ-cell tumor of the orbit and nasopharynx identified as an endodermal sinus tumor (yolk-sac carcinoma). Endodermal sinus tumors arising in extra gonadal locations are highly malignant and generally lethal. The boy was treated with radiation and three-drug chemotherapy and has(More)
Papillomas of the lacrimal canaliculus are very rare tumors and, when encountered in clinical practice, usually present with unilateral epiphora due to obstruction of the lacrimal drainage system. Surgical excision is usually curative although, on occasion, they may recur. The following case report concerns a patient with autosomal-dominant ichthyosis(More)
Because there are no data concerning the association between periocular molluscum contagiosum (POMC) and toxic conjunctivitis, and since there are no established guidelines of acceptable treatment, we surveyed pediatric ophthalmologists in North America in order to analyze the results of their cumulative experience dealing with the disease. Approximately(More)
The problem of acute infectious corneal disease in Bangladesh is discussed. Environmental situations combined with socioeconomic conditions create significant blindness due to this disease in this country. Clinical differentiation into bacterial and fungal ulcers was usually impossible in the advanced stages of ulceration with which the patients presented.(More)
Tumor from eight enucleated eyes was analyzed by immunohistochemistry, using a panel of specific antibodies including interphotoreceptor retinoid-binding protein (IRBP), S-antigen (S-Ag), opsin, neuron-specific enolase (NSE), glial fibrillary acidic protein (GFAP), laminin, and vimentin. In addition, immunoelectron microscopy and enzyme-linked immunosorbent(More)
Three children with histopathologically diagnosed sclerosing endophthalmitis presumably secondary to Toxocara canis were studied by orbital computed tomography. The diffuse increased intraocular density present in the CT scans was indistinguishable from that observed in Coats's disease and non-calcifying retinoblastoma. Although retinoblastoma constitutes(More)
Monozygotic twin girls concordant for Brown's syndrome with reversed asymmetry are presented. This appears to be the first report of concordance for the presence of Brown's syndrome in twins. Embryological factors and a possible explanation for the etiology of this condition in the form as presented are discussed.
Objective measurement of the optic nerve head (ONH)-foveal angle, representing the torsional status of 40 eyes in 20 normal patients, was performed by fundus photography and compared to a method utilizing an indirect ophthalmoscope and protractor described herein. Photography established a mean ONH-foveal angle of 7.03 degrees (SD 2.94 degrees). Comparison(More)
